Descriptive Information
Brief Title Establishment of an Algorithm for a Clinical Classfication of Hypoosmolar Hyponatremia
Official Title Not Provided
Brief Summary The prospective clinical diagnosis of hyponatremia is often very difficult- but requirement for an appropriate and riskless treatment of hyponatremia. This study try to establish an algorithm handling a prospective clinical categorization of hyponatremia and approving together the start of an appropriate symptomatic therapy.
